Media Lab today announced that AlphaMania and the Effector Sets are now available for Mac OS X. “AlphaMania 2 + Effector Sets are the only tools that allow Director authors to include video-style special effects that render and composite live on stage as their project is playing,” said Chris Perkins, CEO of Media Lab. “This means that the effects can react to what the end user of the Director movie does, enabling a uniquely memorable interactive experience. Imagine a pond that ripples only where the end-user places the cursor or a single graphic of a car that can have paint of any hue based on user selection.” AlphaMania 2 + Effector Sets are priced at US$199.
